Abstract

The invention relates to the technique of installing radio elements on printed circuit boards, in particular, to devices for installing multi-output radio elements on printed circuit boards. The purpose of the invention is to improve the performance and quality of the installation of radio elements - due to the fact that the terminals of the radio elements are located between the teeth 3 and 4 of the combs 1 and 2. The combs are fixed between each other by projections 7 and 8 located on the side walls 5 and 6, and fix the body of the radio element to the side walls 5 and 6 of the combs with a fastening element made in the form of an elastic U-shaped element 15. After inserting the ends of the radio element into the holes of the printed circuit board, it is mounted on the printed circuit board, moving along Shackle walls 5 and 6, and then removed the elastic member 15 and the combs 1 and 2 z.p.f 2.

The invention relates to the installation of radio elements on printed circuit boards, in particular, to devices for installing on the printed circuit boards, mm output radio elements,

The purpose of the invention is to improve the performance and quality of the installation of radio elements.

Fig, 1 shows the proposed device; Fig. 2 shows the terminals of the component radio element fixed in the holes formed by comb-shaped plates superimposed on each other; Fig. 3 shows the installation of a radio element on a printed circuit board using the proposed device (side view), and Fig. 4 is the same (front view).

The device for installing multi-lead radio elements contains combs 1 and 2 with inclined, towards the longitudinal axes of the combs, teeth 3 and parallel to each other.

4c wedge-shaped bevels at the ends. Combs 1 and 2 are made with side walls

5 and 6, on which the protrusions 7 and 8 are made. They are located above the teeth of the comb. The protrusions 7 and 8 intended for fixing the dies limit movement of the dies 1 and 2 along the terminals 9 of the radio elements 10 when mounted on the printed circuit board 11.8 of which holes 12 are made for the terminals of the radio elements.

In the side walls 5 and 6 of the dies 1 and 2 are viewing windows 13 and 14.,

The device is equipped with means for fastening the radio elements to the combs 1 and 2, made in the form of a U-shaped elastic element 15. For ease of use, the side walls 5 and 6 of the combs 1 and 2 are made with handles 16 and 17.

The device works as follows.

The comb 2, holding the handle 16, is inserted, having its plane with the teeth 4 perpendicular to the terminals 9 of the radio element 10. The teeth 4 into the gaps between the terminals 9 of the radio element 10 (closer to the base of the terminals 9) up to the stop so that the electronic component housing 10 was against the wall 6. Then, similarly, holding the handle 17, insert the comb 1. Then install the fastening element 15, pressing the walls 1 and 2 to the body of the radio element 10. Thereafter, the comb 1 and 2 are moved along the leads 9 to the body radio element 10 in the protrusions 7 and 8. In this case, c Banks 1 and 2 are in contact with their mating planes (with teeth 3 and 4), and above the combs 1 and 2 remain the ends of leads 9 with a length of 1.5-2 mm, thus fixed according to the arrangement of the holes 12 of the printed circuit board 11 (smf.Z). Then the ends of the leads 9 are inserted simultaneously into the holes 12 of the printed circuit board 11, pushing the leads 9 to the desired length through the holes 12 of the printed circuit board 11 and the holes formed by the teeth 3 and 4, are visually controlled through the viewing windows 13 and 14 by passing the leads 9 of the metalized holes 12 of the printed circuit board 11.

After installing the terminals 9 of the radio element in the hole 12 of the printed circuit board 11, the fastening element 15 is removed and the combs 1 and 2 are alternately removed by the handles 17 and 16.
